CLIFTON HADEN ROBERTS, 0F HAZARD, NEBRASKA,

VALVE-LIFTING DEVICE.

Specification of Letters Patent.

Application filed January 13, 1919. Serial No. 270,903.

To all whom it may concern:

Be it known that I, CLIFTON H. Roenn'rs, a citizen of the United States, residing at Hazard, in the county of Sherman and State of Nebraska, have invented certain new and useful Improvements in Valve-Lifting Devices, of which the following is a specific: tion. I

This invention relates to metal working, and more especially to tools employed in assembling; and the object of the same is to produce an improved valve li't'ter for use especially on Ford cars.

The invention as a whole is a neat, serviceable, and inexpensive tool adapted for ready application and adjustment, and its details of construction are fully set forth in the-following specification and claims. In the drawing- Figure 1 is a sectional view through a portion of a cylinder, showing this valve lifter in use.

Fig. 2is a perspective view of the lifter on a larger scale.

The well. known parts shown in Fig. l. are the cylinder (7 and its piston l", the valve whose head is indicated at ll and whose stem or rod is lettered R. the coiled spring on the rod lcttcreds, and the washer \V for sustaining the spring. N0 novelty is clain'ied for these parts. i

The valve lifter best seen in Fig. 2 is by preference constructed as follows: A foot 1 is splitat its outer end into two tongues 2 upturned at their extremities into claws 3,

'alve and the slot 4: between the tongues is enlargcd at 5 to loosely receive the valve rod It between the inner end (3 of the slot and its mouth, the slot at all points being sutficicntly wide to rcccivc, the pin 7 which passes throu h the rod llbeneath the cupped washer I Therefore, it will be seen that this forked t'oot. may be passed astridc the rod direc ly in line with the pin 7 it de sired and as shown in Fig. 1, or transvcrselv to the pin. it prclcrrcd.

The other end-oi the foot is bent upward into a channclcd arm 10 having its edges turncd ovcr into longitudinal gllidcs ll. Slidably mounted along this arm and hc twccn its uidcs is a ton 'ue 12 iicnt at its upper end at right angles as at lil so as to stand substantially parallel with the tool. This uppcr portion 12% is connected with the foot by means of a bolt 14 whose head 15 underlies the foot as seen in Fig. l and avhose threaded upper end 16 receives a thumb nut 1.7 and a washer l8.

Over-lying the horizontal upper-"end 13 of said upper member is a head iiidicated broadly at 20. Its body is slotttd as at 21 and ad justably mounted aStride the bolt and over the upper portion 13 and its inner end is cupped upward as at 22 and preferably stamped with a longitudinal rib 23 for the sake of strength. This end of the head overlies thehead ll of the valve as seen in Fig. 1, while its body overlies the flat portion 13 and may be adjusted beneath the i'aslier 18 as will be clear.

The valve litter is used as shown in Fig. 1. The claws of the foot 1 pass astride the valve rod R under the spring washer W as shown, and the cupped head 22 overlies the head H of the valve as also shown. Now the thumb nut 17 is turned on the threaded end 16 ot' the bolt to draw the horizontal members oi this tool toward each other, as is permitted by the telescoping of the tongue 12 into the guide arm 10. and very soon the spring J is put under tension so that it contracts a little and the foot 1 is lifted oil the pin 7. The valve lifter is removed by a reversal of the operation in a manner which will be clcar. v

The foregoing description and the drawings have reference to what may be considered the preferred form of my invention. it is to be understood, lunvever that I may make certain changes in construction and ar rangcmcnt of parts, materials. dimensions. ct cctcra. as may prove expedient and tall within the scope of the appended claims.

llaving thus fully described my invention, what T claim as new and dcsireto secure by Letters Patent. is:

i. The herein described automobile valve lifter comprising a foot. a head, telescoping clcmcnls connecting these members. a'. bolt standing parallel with. said elements and also connecting said mclnbers, and a thumb nut on the bolt. i

2. A val vc li l'tcr comprising a foot lorlted at its outer cud and having its l'orl -arms uplurncd into claws, a hcad slotted longitudinally in its body and having its outer cud cuppcd upward. iclcscupic. conncctions bclwccn lhcsc mcndu-rs. and n ans for drawing lllc nu-mbcrs toward each other, and said lncans passing through said slot for adjustably holding aid head upon one of said connections, as described.

Patented Sept. 23, 1919.

no i P I 3. A valve lifter comprising'a foot forked at its outer end and havingits fork-arms upturned into claws, a head slotted longltudinally in its body and having, its outer end cupped upward, an arm upstanding rigidly from the inner end of said foot and provided with guides, a tongue depending from beneath the head, and slidably mounted in said guides and means for drawing the head toward the foot, and said means passing through said slot for holding the head in an adjusted position upon said tongue, as

' described.

,tongue slidably mounted in said guides and 4. A valve lifter comprising a foot forked at its outer end and .having itsLfork-arms upturned into claws, a head slotted long-'i tudinally in its body and having its outer end cupped upward, an arm upstanding rigidly from the inner end of said foot and provided with channeled guides along its edges, a tongue slidably mounted in said guides and havingoits' upper end turned at right angles and underlying the head, and

a bolt through this head and the upper portion of the tongue and foot and slot of said head, for the purpose set forth.

5. In a valve lifter, the combination with afoot having aslot in its outer end and its inner end upturned and provided with guides, a right angular member having a its upper portionparalleling said foot, and

' a bolt through said upper portion and having a thumb nut; of a head having a slotted body overlying said upper portion and with its slot passing astride'said bolt, its inner end being-cupped. i

6. In a Valve lifter, the combination with a foot having its outer endslotted and the slot enlarged between, its extremities to a size to receive the' valve rod, and a, head having its innerend cupped upward and of a size to receive the valve head; of telescopic elements connecting these members, and means for drawing'the members toward each other. v

71 In a valve lifter, the combination with a foot having its outer end slotted-and the slot enlarged between its extremities to a. size to receive the valve rod, and ahead having its inner end cupped upward and of a size to receive the valve head of an 'arm up- Standing fromthe inner end of the foot, a

prising a foot, a head, telescoping elements connecting these members, and means standing parallel with said elements and also connecting said members for drawing the same toward each "other, as described.

In testimony whereof I afiix my 'sig'nature in presence of two witnesses. N
